Definitions

  • the present invention relates to a felting apparatus for felting fiber materials and to felting methods and to an article made by felting.
  • the felting of fiber materials in particular wool materials has been known for a long time and it is basically a distinction between two felting techniques, the dry felting and the wet felting. In both techniques, the shorn, washed, dried and combed raw wool sheared by the sheep is in principle processed in such a way that the result is, in particular, a closed, firmly bonded felt layer or felt form.
  • fibrous materials are to be understood below as meaning all materials made from fibers, in particular comprising both raw material and processed material. In the case of processed material this may in principle have any shape.
  • fiber materials include, in particular, wool, such as sheep wool, yak wool, alpaca wool and also angora, to name only a few examples.
  • fiber materials also include vegetable materials such as cotton or hemp fibers.
  • fiber materials may involve artificial, industrially produced materials.
  • the present invention relates to dry felting. When dry felting, for example, with a about 8 cm long, triangular-ground felting needle, which has barbs at the top, repeatedly stung in the raw wool.
  • Another disadvantage of such machines is that it is practically not possible to felt hollow object in which something is to be felted, for example, to an outer layer or wall of the hollow object.
  • a slipper for example, there is a risk that when trying to felt something on its upper side, it could become undesirably felted with the lower side.
  • the object of the present invention was therefore to reduce or eliminate at least one of the problems described above, or to propose a solution which To facilitate manual felting while avoiding the disadvantages of previously known felting devices as possible. At least an alternative solution should be proposed.
  • a felting device for felting fiber materials according to claim 1 is proposed.
  • Such a felt device thus comprises a needle holder for receiving and holding a felting needle for performing the felting.
  • a known felting needle can be picked up and held with its rear side in the needle holder.
  • such felt needles are interchangeable.
  • the felting device comprises a drive motor for moving the needle receptacle to thereby ultimately move the inserted felting needle.
  • a drive motor for moving the needle receptacle to thereby ultimately move the inserted felting needle.
  • an oscillating movement of the needle holder with inserted felt needle is provided in the longitudinal direction of the felting needle.
  • the drive motor is preferably designed as an electric motor.
  • other engines come into consideration, such as a drive through a spring accumulator with retractable spring such as a wind-up spiral spring similar to a mechanical clock.
  • a housing is proposed for movably holding and guiding the felting device with one hand. This makes it possible to guide the felt device with one hand on the object to be felted at the desired location or the desired area along and perform felting by the oscillating felting needle.
  • the size and shape of the object to be felt is basically not important.
  • the felt device according to the invention can also be referred to as a hand felting device or mobile hand felting device. It is preferably twice as fast as a commercially available, described above felting device.
  • the hand felting device according to the invention is particularly small, handy, lightweight and portable. With their handy, lightweight design, an energy-saving design can be achieved.
  • the felt device With the felt device according to the invention, it should now be possible to basically felt or felt any size, small, three-dimensional and Hohlgorgee. Due to the design, it is possible that there is a large radius of action on all sides, since the hand felting device with its housing is intended in one hand and the operator can thus felt around the object in question. It is not necessary to move the object to be felt, as with the machines described above. Especially at This can be a big advantage for very large, heavy, unwieldy and even very small objects. Because of the size and lightness of the hand-felting hand-held device, it can basically be used anywhere. If there is no energy store for operating the anti-friction motor in the hand-felting device itself, the necessity of an electrical connection also limits the area of use.
  • the hand felting device according to the invention can also be readily used, for example, outdoors.
  • felting hollow objects can be facilitated because the user, with the felting device in his hand, can more accurately determine or control the puncture depth of the needle.
  • the risk of piercing the needle through a cavity into an opposite side and thus undesirably achieving felting through the cavity can thus be eliminated, but at least reduced.
  • the housing can preferably accommodate all elements of the felting device, so that substantially only the felting needle projects in part out of the housing.
  • the elements of the felting device completely absorb, but is not a mandatory requirement for the housing. Rather, the felt device is to be performed on it with one hand and insofar can be provided instead of the housing or in addition to a holding means for movably holding and guiding the felting device with one hand.
  • the felting device is characterized by a guide means for axially guiding the felting needle and / or the needle receptacle.
  • the guide means may for example be a guide shaft, in particular a cylindrical guide shaft, in which the felting needles and / or the needle holder slides in the axial direction.
  • the needle receptacle is guided so that the guide means may be substantially independent of the size and shape of the felting needle, and no problems of slidingly guiding the barbs of a felting needle occur. In such a case, the felting needle can simply be exchanged for a new one and / or another one if necessary, without having to influence the guidance.
  • a felting device which is characterized in that a hinge connection, in particular a universal joint, for coupling the Needle holder is provided with the drive motor to deflect a non-axial movement, due to a rotational movement of the drive motor, in an axial, oscillating movement of the felting needle.
  • a rotational movement of the drive motor can be converted into a substantially translatory, ie axial, movement similar to a crankshaft and connecting rod.
  • a joint connection with a simple joint can be sufficient.
  • the use of a universal joint provides a greater tolerance to a divergence in the upstream driveline and can compensate for tolerances.
  • a simple and space-saving design can be enabled, whereby the inventive guiding the felting device is facilitated with one hand.
  • This makes it possible to achieve an axial or linear movement using a commercially available, rotating motor, in particular electric motor.
  • a linear motor can also be provided which directly effects the desired linear oscillating movement. This can be achieved, for example, by means of two electrical coils, which cause the oscillating movement by alternately energizing.
  • a key switch for switching on and off of the drive motor and / or for starting and stopping a needle movement of the felting needle is proposed.
  • the felting needle moves with the push button pressed and stops moving as soon as the push button switch is no longer pressed.
  • the key switch thus allows easy handling and is preferably arranged so that it can be operated simultaneously with the same hand with which the felting device is held and moved.
  • the key switch is arranged directly on the housing.
  • the felting device can thus be operated in a simple manner with one hand and be switched on and off almost at will. In particular, frequent settling of the device in one area and restoring it in another area is simplified.
  • the tactile switch is thus intended to control the movement of the felting needle. This can be done by starting or stopping the engine or even an intervention elsewhere, such as by the breaking of the drive train between the engine and felting needle.
  • a felt device which is characterized in that the drive motor is designed as an electric motor, in particular as a DC motor, and / or is supplied with electrical current via an energy store, in particular a battery or accumulator, received in the housing.
  • an electric motor provides a simple realization possibility of a hand felting device.
  • a switch such as a button
  • the power supply to the electric motor can be closed or interrupted, thereby starting or stopping the motor and thus the movement of the felting needle.
  • an energy storage device such as a battery or a rechargeable battery
  • the felting device becomes independent from an external power supply and annoying cables can be dispensed with.
  • a DC motor can be easily coupled to a battery or a rechargeable battery, since these also provide a DC voltage or a direct current.
  • the guide means for axially guiding the felting needle or the needle receptacle opens with a front end into a housing opening or such a front end forms a housing opening.
  • the construction should be designed in such a way that the felting needle is pushed out of this opening in an oscillating manner when used as intended for felts and pulled in again.
  • the felting needle can in each case be pulled so completely into the opening that it no longer protrudes from the opening in the pulled-in state.
  • the felting device for felting with this housing opening can be guided along the area to be felted of the object to be felted. In particular, a uniform felting is thereby made possible in a simple manner. It is favorable if the felting device is characterized in that the length by which the felting needle protrudes maximally from the or a housing opening during a movement for felting is favorable.
  • the penetration depth of the felting needle can be adjusted in the object to be felted.
  • This penetration depth corresponds to the length by which the felting needle protrudes maximally from the housing opening when the housing opening is guided directly on the surface of the object to be felted.
  • the protrusion can then be adjusted. For example, when felting two superimposed felt layers, their total thickness can be set as the length by which the felting needle protrudes maximally out of the housing opening.
  • such adjustability also makes it possible to adapt the felt device to felt nippers of different lengths.
  • the adjustability can be achieved for example by a telescopic opening or by a change in the position of the needle holder within the felting device, for example by the distance between the needle holder and connection to the engine is shortened or extended. Also, the distance between or a joint connection such as a universal joint to the needle holder can be designed adjustable for this purpose.
  • the stroke length which can also be described as oscillation amplitude, can also influence the movement length within the material to be felted.
